???????????? ? long-distance

?????????????? 句中含有連字符

National and regional online systems usually have local telephone numbers that PC modems can call to access either a local information base or an indirect long-distance connection, thus reducing long-distance telephone fees. Some online systems allow users to copy large volumes of information onto a local memory storage device, which also reduces the time the user is connected to the online system.
國家或者是地區(qū)級(jí)的在線系統(tǒng)通常有本地的電話號(hào)碼,PC路由器能夠通過撥號(hào)進(jìn)入本地信息庫或者間接長途連接,因此減少了長途電話費(fèi)用.有些在線系統(tǒng)允許用戶拷貝大容量的信息到本地存儲(chǔ)裝置,這也減少了用戶連接在線系統(tǒng)的時(shí)間. ——譯文來自: Tim_WTH
